In each of Exercises, we have given the number of successes and the sample size for a simple random sample from a population. In each case, do the following tasks. a.Determine the sample proportion.b.Decide whether using the one-proportion z-interval procedure is appropriate.c.If appropriate, use the one-proportion z-interval procedure to find the confidence interval at the specified confidence level.d.If appropriate, find the margin of error for the estimate of p and express the confidence interval in terms of the sample proportion and the margin of error. x = 10, n = 40, 90% level
